3512E Tier 4 / IMO III
3512E Marine Propulsion Engine (U.S. EPA Tier 4 Final)
DESCRIPTION
The 3512E marine propulsion engine is now available in a wide range of ratings that meet U.S. EPA Tier 4 Final and IMO III marine emissions regulations. As the commercial marine industry adjusts their operations to meet U.S. EPA Tier 4 Final and IMO III emissions standards, Caterpillar Marine has introduced a solution built to maximize performance while meeting regulations. Caterpillar's combination of a fuel-efficiency-optimized engine and a selective catalytic reduction (SCR) aftertreatment system is a solution that not only reduces NOx emissions, but can also lower a customer's owning and operating costs in the process.Emissions
Utilizes SCR Technology to enable U.S. EPA Tier 4 Final emission regulations compliance while lowering operational costs, IMO III emissions compliant
Utilizes closed loop air assisted DEF dosing control strategy
Highest efficiency mixing and control to lower operational costs, extends emissions useful life, ensures compliance, flexibility regarding urea quality
